You don't need more filming hours, you need more *outputs* per hour. Mine the hook before you film, atomise one long-form into a dozen platform-native shorts, and let the retention curve, not your taste, decide what to make next.
Mine the hook before you film, batch-film long-form, then atomise each piece into platform-native shorts that fan out across YouTube,
TikTok and Reels, and let retention, not taste, pick the next topic. Not doing: filming shorts separately or cross-posting one identical export to every feed.
